refer to https://github.com/pytorch/ao/pull/1677
This pull request includes several changes to improve compatibility and support for new GPU architectures and data types, particularly for ROCm. The key updates involve adding support for new ROCm versions and GPU architectures, updating data type handling, and removing outdated checks.
### Improvements to GPU Architecture and ROCm Version Support:
* [`aten/src/ATen/Context.cpp`](diffhunk://#diff-33de472d304acbe57d693c8567370c638068bedc1aa0ce8e9dc115dad05a7810L323-R326): Added support for new GPU architectures `gfx1200`, `gfx1201`, and `gfx950` based on ROCm version checks.
* [`aten/src/ATen/native/cuda/Blas.cpp`](diffhunk://#diff-e8a569efee1e650172f120a0fdcda024fe3e4703a4ee3336425c8f685af6b3abL196-R199): Updated architecture support in multiple functions to include `gfx1200`, `gfx1201`, and `gfx950` based on ROCm version checks. [[1]](diffhunk://#diff-e8a569efee1e650172f120a0fdcda024fe3e4703a4ee3336425c8f685af6b3abL196-R199) [[2]](diffhunk://#diff-e8a569efee1e650172f120a0fdcda024fe3e4703a4ee3336425c8f685af6b3abL865-R876)
### Updates to Data Type Handling:
* [`aten/src/ATen/cuda/CUDADataType.h`](diffhunk://#diff-9188bb13b1a49f459141f5f9b875593d1c5ce2beb5ad711fdbaf5bc7089ec015L81-L98): Enhanced data type conversion to include new float8 types for both CUDA and ROCm environments.
* [`aten/src/ATen/cuda/tunable/GemmHipblaslt.h`](diffhunk://#diff-bfa1a3b5d4bef1892bf50338775f3b0fd8cd31fc1868148f3968b98aefb68e3fL29-R80): Updated `HipDataTypeFor` template to handle new float8 types and added hard-coded enum values for ROCm versions prior to 6.3.
### Removal of Outdated Checks:
* [`cmake/public/LoadHIP.cmake`](diffhunk://#diff-b98e27b9a5f196a6965a99ee5a7bb15b3fc633d6375b767635b1b04ccb2fd3d5L169-L197): Removed the check for `HIP_NEW_TYPE_ENUMS` as it is no longer necessary with the updated ROCm versions. [[1]](diffhunk://#diff-b98e27b9a5f196a6965a99ee5a7bb15b3fc633d6375b767635b1b04ccb2fd3d5L169-L197) [[2]](diffhunk://#diff-b98e27b9a5f196a6965a99ee5a7bb15b3fc633d6375b767635b1b04ccb2fd3d5L211-R182)
These changes ensure better compatibility and performance on newer hardware and software environments, particularly for users leveraging ROCm and CUDA for deep learning and scientific computing tasks.

State after this IR:
1. For the tests that require inference IR, they are replaced with ep.run_decomp({}) so export_for_training_run_decomp is sort of redundant but i guess it is still nice that multiple round of retracing still working. In general, we need some auditing to reduce our redundant testing coverages.
2. After this PR landed and not get reverted for a week or so, i will replace the export_for_training calls with export as they are the same thing now.
3. Added more tests to also cover now "deprecated" old IR by patching export to use old export. For reviewers, please look at the internal version.

Previously: https://github.com/pytorch/pytorch/pull/138052 but the implementation is done from scratch, so I open a new PR.
This implements the ability to save and load profiles of automatic dynamic decisions, so on subsequent runs we can directly make something automatically dynamic. Unlike the previous implementation, this cache is never enabled by default; instead, you have to specify a "job id" that says it's OK to share results. We will be able to automatically populate this id for internal MAST jobs but for generic OSS users you will have to explicitly opt into it.

This teaches install_config_module (and the underlying code) to
understands Config objects. Additionally we've added a JK option to this
which resolves the JK.
This config gets stored within the _ConfigEntry class and is evaluated
when __getattr__ is called. If justknobs is set, it'll call
justknobs_check to see the result.
Due to preceeding work, basically everything works correctly here and we
had to update a couple of tests, and modify the getattr behaviour.
Note that we are updating the justknob_check function to support a
default option, to make default work.

This diff does a few things:
## Add metadata to events in progress
Adds the ability to add extra metadata to Chromium Events via `add_event_data`.
Metadata can only be added to chromium events that have started, but not ended (so, in progress events)
- When you add the data, the metadata is appended to the metadata when you call log_event_end().
- The metadata appears in chromium events in tlparse. It also gets logged to scuba.
## New `dynamo` chromium event
We add a new `dynamo` chromium event to the top of the stack, where we collect various metadata found in dynamo_compile. So the new order of events goes:
```
__start__
-> dynamo (dynamo compile metrics)
-> entire_frame_compile (compile.inner)
-> backend_compile (i.e. aotdispatch)
-> create_aot_dispatch_function
-> inductor_compile
-> ...
```
BackwardCompilationMetrics doesn't have any dynamo specific information (as it's mostly inductor timings). So we don't include that here.
*FAQ: Why can't we use `entire_frame_compile` as the event?*
This is mostly due to backward compatibility with `dynamo_compile`. `dynamo_compile` collects CompilationMetrics outside of `compile.compile_inner`, and uses `dynamo_timed` to grab timings from phases of the compiler, including `entire_frame_compile`. So we don't have a CompilationMetric object until after an `entire_frame_compile` event ends! Separately, `dynamo` as a name for all of dynamo compile is more descriptive than `entire_frame_compile`, imo.
## Log metadata as separate columns
(Meta only): Separately, this also changes the `metadata` column in PT2 Compile Events. Instead of logging a single metadata column in JSON, it separates the JSON into separate columns. This is much better for data analysis. Now that this table is more mature, I think logging keys to separate columns is a better system.Differential Revision: [D64696287](https://our.internmc.facebook.com/intern/diff/D64696287/)

Type annotations for compile_fx.
- Some of the stuff here is pretty complicated (functions which return functions that take functions) so I bailed on those and used `Any` just to get the rest landed.
- There are also changes to type signatures in other files which I did just to let mypy know more about the types in compile_fx.py.

This diff is the starting steps of https://docs.google.com/document/u/2/d/1kAEBt4AyW7HTAhXHbjoz8FBFHNyyEA2Qo2mPn7v3WUQ/edit?usp=drive_web&ouid=113555078003219714709
It implements the following changes:
- Only log spans to scuba, so no start events are ever logged
- Log events as the full event name, without "START" or "END"
- Only log to scuba major phases from chromium events. These are:
- entire_frame_compile (dynamo)
- backend_compile (aotdispatch)
- inductor_compile (inductor)
- codegen (inductor codegen)
Tlparse chromium events stay basically the same. But I implemented a few changes to clean that up as well:
- When there's a phase name available, log the phase name instead of the function name as the event name. This simplifies the trace to not have two identical rows. The fn_name is avaliable as metadata on the chromium event, if interested
- Log new events for pre and post grad passes. These do *not* log to scuba.
By making the phases much simpler in Scuba, with only categories for major phases of PT2 Compilation, we pave the way to add **much** more metadata and information to each individual event type. Diffs for that will come later.
**IMPLEMENTATION NOTES:**
- The logic for `log_chromium_event_internal` (which is the function that logs to Scuba) lives in chromium_events for now, but in the future as we add more metadata, it may belong independently in dynamo_timed or even outside of dynamo_timed. I haven't explored in detail what the refactor will look like. Once we start logging metadata for dynamo, aotdispatch, inductor, I suspect we will call log_pt2_compile_event directly, instead of making chromium event logger handle the pt2_compile_event logic. But that refactor is left for another PR on top of this one.
- There's an interesting space after pre grad passes within AOT autograd logic, that's between create_aot_dispatcher_function and pre grad passes. I'm not sure what we're spending time doing in that time, but I'll find out with a profile later.

Summary:
Move towards consolidating strobelight profiler implementations between OSS and fbcode. This change is a first step towards that.
- Created a new function to abstract out compile time profiling enablement. This function allows profiler to switch between different function profilers (e.g. Thrift based or CLI based)
- Both OSS and Fbcode now use one compile time profiler in torch/_strobelight
Test Plan:
Tested OSS with following commands:
```
python torch/_strobelight/examples/compile_time_profile_example.py
python torch/_strobelight/examples/cli_function_profiler_example.py
TORCH_COMPILE_STROBELIGHT=TRUE TORCHINDUCTOR_FORCE_DISABLE_CACHES=1 python benchmarks/dynamo/huggingface.py --ci --accuracy --timing --explain --inductor --device cuda --training --amp --only XLNetLMHeadModel
```
See test commands for fbcode in comments.

This is designed to be a more ergonomic interface on top of justknob_feature (see https://github.com/pytorch/pytorch/pull/134151 for just the PR with the base commits).
The idea is that people stop having to think about this as much, and can just do JustkobsConfig("//the:thing", "FORCE_THING") and it'll do the right thing.
Primarily sending this to see how people feel about the API, and using it for new config changes.

Summary:
Make quantization tests compatible with the new training IR.
With the new batch norm node `torch.ops.aten.batch_norm.default`, we don't need an additional getitem node after the bn node, so tests need to be fixed to not check for the getitem node.
We added a capture_pre_autograd_graph_using_training_ir() function, which returns True when we are using the training ir, and False otherwise. This way, the code supports both training ir and the old ir.
For now, we are just rolling out the training ir for fbcode internal tests.

Summary:
This diff implements a bunch of views for internal scuba viewing.
TODOS that I might punt to another diff:
- Saving cache stats via counter is definitely sus here, but there's not really a good way to track "fx graph cache hit for this compile phase" right now. Will think about this more.
- We should definitely log frame id, compile id, etc
- We should definitely be logging configs. That way, we can A/B test based on whether a config is turned on.
- idk what I'm doing with compile_uuid yet, but it's useful when you want to look at samples for a single run. I think if we had mast job info this field is not needed, but it's nice to be able to drill down to a single run and get its chrome trace view or icicle view, so idk
Test Plan:
All of the above views are run with nanogpt benchmark:
```
buck run mode/opt caffe2/benchmarks/dynamo:torchbench -- --training --backend=inductor --only nanogpt --performance
```

Previously, if someone used `register_fake` to add a fake impl for an
operator defined in C++, we would require them to add a
`m.set_python_module(<module>)` call to C++. This was to avoid
situations where a user imported the C++ operator without importing the
fake impl.
This "breaks" open registration: there's no way to add a fake impl
outside of a repository that defines an operator, so we want to turn
this behavior off by default in open source.

ghstack dependencies: #123937
This PR:
- adds a new torch.library.register_fake and deprecates
torch.library.impl_abstract. The motivation is that we have a lot of
confusion around the naming so we are going to align the naming with
the actual subsystem (FakeTensor).
- renames `m.impl_abstract_pystub("fbgemm_gpu.sparse_ops")` to
`m.has_python_registration("fbgemm_gpu.sparse_ops")`. No deprecation
here yet; I need to test how this works with static initialization.
- Renames a bunch of internals to match (e.g. abstractimplpystub ->
pystub)
I'm scared to rename the Python-side internal APIs (e.g.
torch._library.abstract_impl) because of torch.package concerns. I'll do
that in its own isolated PR next just in case it causes problems.
DEPRECATION NOTE: torch.library.impl_abstract was renamed to to
torch.library.register_fake. Please use register_fake. We'll delete
impl_abstract in a future version of PyTorch.
